To all 'whom', z't may camera:

Be t known that I, JOHN A. LANoAsrER,

.a citizen of the United States, residing in Jersey City', in the county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Typewriter Sheets, of which the following is a specification.

The invention relates to sheets written upon in writing machines and more particularly to the sheets of paper written or printed upon in typewriting machines.

In the operation of a common form of writing machine, the typewriter, the sheet of that is to say, Carry the writing beyond the desired or proper. limits.

Various instrumentalities have been provided to warn the operator of the approach of the end of thesheet, such instrumentalities taking the form of mechanical devices to be attached to the typewriter or to the sheet itself. But such devicesare objectionable on various grounds, as for reasons of economy, Simplicity of Construction, or convenience of operation.

With the foregoing defects in mind, therefore, objects of the invention are to provide means for warning the operator of the approach of the end of the sheet, which means shall be economical, of extreme Simplicity, and unfailing in operation.

The invention consists in providing a sheet of material, as paper, for use in a writing machine, as a typewriter, which e sheet shall contain in itself the means for warning the operator of the' approachof v the end of the sheet.

Inone form of the invention, a sheet-of typewriter paper i provided which has a water-mark sutably disposed thei-ein which acts as suchsignal or warnng means.

In another form of the invention, a sheet of writing material is provided which has side marginal lines, such lines being brokenat a suitable place to furnish the desired signal or warning to the operator.. I

These and other forms of the invention will be more fully set forth in the following description.

In the drawings which are referred. to

herein and made part hereof are illustrated i several embodiments of the invention, the same serving to illustrate the invention and `make clear the principles thereof.

Of the drawings':

Fig. 1 is a plan of a sheet of typewriter ipaper having a water-marktherein to act as a signal for the purpose described;

Fig. 2 is a similar view with a water-mark of different design;

Fig. 3 is a. similar view of a sheet having broken side marginal lines, the break acting as the signal; and

Fig. 4 is a similar view in which a watermark is shown near the top and bottom of the sheet, respectively.

Referring now in detail to the invention, there is illustrated in Fig. 1 of the drawings one embodiment of the invention, the same comprising a sheet of paper having at a suitable dstance from the bottom or end thereof a Physical peculiarity sufliciently striking to catch the eye of the operator and thereby act as a signal to the operator that the end of the sheet is approaching, the operator thereby being enabled to conform the work accordingly.

As shown, this physical peculiarity consists of a water-mark 7 in the paper extending horizontally across the sheet a substan- -tial distance and being of a suitable width.

It will be noted that the water-mark may be of any suitable design or dimensione, the mark in Fig.,2, for example, showin the word End, the intent of the same %eing readily apparent. These letters may be of any suitable size and design and spaced apart as desired. It will be further observed that the mark may be of various other things.

In using sheets of paper with entirely blank surfaces and which sheets may be used with either end serving indiferently as the top or bottom, each end'may be rovided with the warni water-mark, ma e in the paper at a suita le distancetherefrom, as

shown in Fig. 4, thus obviating any possible' natures, if desired, to indicate various.

A modification of the invention is shown in Fig. 3, in `which is illustrated a sheet ofpaper having side margin al lines, said sheet being in common use. In the case of this sheet the marginal lines may be broken or interrupted .at a suitable distance from the bottom of the sheet and to a suitable extent, the break 9 in the lines serving as the desired signal mark or warning 'to the operator. Preferably and as shown, the marginal lines at both sides of the sheet are thus broken, thus making a signal at each side of the sheet to attract the attention of the operator Itwill be seen that a sheet of typewriter paper fashioned according to the principles of the invention as herenbefore set forth r will carry out the objects of the invention as u enumerated and also possesses other advantages, as, to indicate the ownership oiorigin of the sheet, or to serve advertising purposes.

The inventi'on in its broader aspects is not limited to the precise embodiments set forth and described as many changes may be made in the details without departing fromthe spirit of the invention or sacrificing'any its chief advantages.

I. claim:

1; A sheet of paper for use in a writing machine, having near one end an isolated 'discernible physical peculiarity to indicate the approa'ch of the end of the sheet when the sheet is being written upon, said physical peculiarity being spaced at a definite predetermined position from the end of the sheet so that the operator may be enabled, when discerning the physical peculiarity, prap-- *that the operator; may be enabled, when discerning the mark,-properly to gage the work and thereby avoid overwriting the sheet.

i 3. A sheet'of paper for use in a writing machine, having near one end an isolated water-mark to' indicate the approach of the end of the sheet when the sheet is being written upon, said mark being spaced at a definite predetermined position from the end ofthe sheet, sothat the operator may be enabled, when discerning the mark, properly to gage the'work and thereby avoid overwriting the sheet.

4..A sheet of paper for use in a writing machine, having near each end an isolated mark to indicate the approach of the end of the sheet when the sheet is\ being written upon in either of its reversed positions, each of said marks being spaced at a definite predetermined position from the end of the sheet,.so that the operator may be enabled, when discerning the mark, properly to gage the work and thereby avoid overwriting the sheet. In testimony whereof,.I name to this specification.
